As a general part, valve is an indispensable part of major technical equipment, especially in systems of power, petrochemical, metallurgy, fertilizer, environmental protection, urban water supply and drainage, valves plays a key role in fluid control.
Chinas urbanization process has led to large-scale infrastructure construction throughout the country, a large number of water supplies and drainage, especially sewage treatment works are at large scale. Including water treatment equipment manufacturing industry has formed a strong water industry. Butterfly valve products corresponding changes in its performance and parameters based on changes in the field of device applications. The city construction system have gradually shifted to the environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and sealing butterfly valve.
In addition, with the increase of Chinas energy construction and development efforts, China has owned the worlds most ultra-supercritical units. To large-scale develop power plant construction, used of large diameter, high pressure safety valve and pressure relief valve. China also needs to develop the steam trap, and the subcritical and supercritical parameters of the development. Metallurgical equipment manufacturing requires a lot of high-temperature, high-pressure valve device. Chinas valve industry development trend provides a good opportunity. Thus, the "12th Five-Year" period Chinas valve has huge market demand and the potential for development of the industry.
At present, the number of valve companies in China is the top one in the world. Large and small valve enterprises have more than 6,000, about 900 valve enterprise the annual output value of more than 5 million Yuan. From a product point of view, the valve industry in China has been able to produce more than a dozen categories of products, such as plug valves, gate valve, globe valve, ball valves, butterfly valves, safety valves, check valves, throttle valves, pressure relief valve, diaphragm valve, trap, emergency shut-off valve, which the maximum temperature reached 570 ℃, the lowest temperature is -196 ° C, the maximum pressure of 600 MPa, the maximum diameter of 5350 mm.
According to official statistics, China has an annual turnover of the valve market up to about 50 billion Yuan, over 100 billion market occupied by the foreign valve companies; especially the valve is mainly dependent on imports of high temperature, high pressure and other critical devices.
Reporters learned that Chinas valve market "cake" is great, but the market is very competitive. As the valve is a low-margin product, valve market prices, while the annual rise and fall, but the magnitude is very small, relatively stable overall. The valve manufacturers are basically in accordance with the reference price of the valve industry compiled by the China General Valve Industry Association pricing. Due to intense market competition, some valve manufacturers even still run in 1996 prices for customers.
More than 10% of the market is occupied by foreign enterprises in the China valve industry. Valve Branch of China General Machinery Industry Association believes that improve the quality of the valve is the key to change this situation.
